I’ve been down the soap-and-water road, too, and honestly, I think you might just have some tray-cleaning superpowers. Either that or my coffee is secretly plotting against me at night. I tried the baby toothbrush thing for a while—felt like I was giving my aligners a spa day every morning—but after a few months, those little yellowish spots started showing up, especially around the edges. No amount of gentle scrubbing seemed to get them out.
Here’s what finally worked for me (and I swear it’s not rocket science): I started doing this weird rotation—soap and water in the morning, then once or twice a week I’d use a mix of baking soda and water (just a tiny pinch, nothing wild). Let it sit for a couple minutes, then rinse like crazy. The first time I did it, I was convinced I’d ruined the trays, but nope—they actually looked clearer. Haven’t noticed any weird tastes either, which was my main gripe with those cleaning tablets. Seriously, who decided “minty plastic” was a good flavor?
I do think rinsing right after eating is the real MVP move, though. If I forget and let stuff dry on there... game over. And yeah, swapping trays on schedule helps too—sometimes I get lazy and stretch it an extra day or two (oops), and that’s when the stains seem to set in more.
The phone flashlight thing made me laugh. I’ve done the same—standing in my bathroom like a detective looking for clues on my aligners. It’s wild how obsessed you get with tiny marks once you notice them.
Anyway, if anyone else is struggling with stubborn stains, give the baking soda trick a shot—just don’t go overboard or you’ll end up with gritty trays. Not fun.
The coffee struggle is real. I swear, my trays have a sixth sense for when I’m about to enjoy a cup—they just soak up every bit of color. I tried the baby toothbrush thing too, and it felt nice at first, but those stubborn little stains always found a way back. I even bought one of those “aligner cleaning foam” things off Instagram, but honestly, it just made everything taste weird for hours.
I haven’t tried the baking soda trick yet, but now I’m tempted. I’ve been paranoid about scratching the trays, so I’ve stuck with dish soap and lukewarm water (and way too much time spent staring at them under the bathroom light). The phone flashlight move… yeah, been there—squinting at every angle like some kind of forensic scientist.
Rinsing after eating is where I always mess up. If I’m out and forget to bring my case or get lazy, it’s like the stains double overnight. And then I get stressed about it and start brushing way too hard, which probably doesn’t help anything.
Swapping trays on schedule is another one. My ortho keeps telling me not to stretch it, but sometimes life happens and suddenly it’s day 17 instead of 14. That’s when the yellow edges hit hardest for me too.
One thing that helped a bit: soaking them in a diluted hydrogen peroxide mix once a week (my dentist said it was okay as long as it’s super diluted and not every day). It didn’t work miracles, but seemed to keep things clearer between tray changes. Haven’t noticed any weird aftertaste with that either, which is a win in my book.
Honestly, glad I’m not the only one obsessing over this stuff. Makes me feel less ridiculous for spending half my morning inspecting plastic in different lighting.

Honestly, I hear you on this one. My kid’s the same—one skipped rinse and the trays look rough. But I gotta admit, I’m a little wary of the hydrogen peroxide thing, even diluted. Our ortho said it can weaken the plastic over time? Maybe I’m just paranoid, but we’ve stuck to dish soap and water, and swapped out coffee for iced tea (still not perfect, but less staining). The struggle’s real, for sure.

I’ve heard the same thing about peroxide—my son’s ortho was pretty clear that even a weak solution can mess with the trays if you use it too much. It’s tempting though, especially when you see how fast it lifts stains compared to regular soap. We tried it a couple times (desperation after spaghetti night...) and honestly, the trays looked great at first, but after a few weeks, they started to get this weird cloudy look. Not sure if that was the peroxide or just wear and tear, but it spooked me enough to go back to dish soap.
Dish soap and water is kind of boring but it works, especially if you’re on top of it. I totally get the struggle when you forget your case or you’re just tired—sometimes rinsing in a public bathroom isn’t happening. My daughter started keeping a travel toothbrush and a tiny bottle of soap in her backpack. She probably uses it half the time, but even that’s made a difference.
About switching from coffee to iced tea—I wish I had that kind of willpower! I gave up on hot coffee during my aligner days because of the stains, but then I started sneaking sips through a straw... not exactly recommended, but desperate times. Still got some stains, but at least they weren’t as bad as before. Honestly, sometimes it feels like you need to choose between having clean trays and having any fun at all.
One thing that helped us was soaking the trays in warm (not hot) water with a denture tablet maybe once or twice a week. The ortho said that’s fine as long as you rinse really well after. It doesn’t work miracles, but it does help with that funky smell and keeps things looking clearer.
The struggle is real for sure—sometimes I think aligners are harder to keep clean than braces ever were...
